PLOW.

SPECIFICATION forming part of Letters Patent No. 765,1 15, dated July12, 1904.

Application filed July 15, 1903.

1'0 all whom, it may concern.-

Be it known that I, LEMUEL MANUEL 71L- HIITE, a citizen of the UnitedStates, residing at Benchley, in the county of Robertson and State ofTexas, have invented new and useful Improvements in Plows, of which thefollowing is a specification.

This invention relates to plows; and the primary object of the same isto provide a device of this class adapted for use with a shovel, sweep,center-splitter, or other plow proper adjustably held by a movablestandard connected to the forward extremity of a rigid shoe-bar, withwhich the rear-depending extremity of the beam also connects, and hashandles ad justably supported thereby to adapt them to be raised orlowered, whereby the plow may be arranged to accommodate plowmen ofdiiferent heights, and also to regulate the depth of cut and inclinationfound necessary in setting the plow blade, share, or sweep.

The invention consists in the construction and arrangement of theseveral parts, which will be more fully hereinafter described andclaimed.

In the drawings, Figure 1 is a side elevation of a plow embodying thefeatures of the invention. Fig. 2 is a top plan View of the same. Fig. 3is a rear end elevation. Fig. 4: is a longitudinal vertical sectionthrough the rear part of the plow. Fig. 5 is a detail perspective viewof the adjusting standard. Fig. 6 is a detail perspective View of theshoebar.

Similar numerals of reference are employed to indicate correspondingparts in the several views.

The numeral 1 designates a plow-beam of elongated form and graduallydipped in a curved line toward its front extremity, where a suitableclevis 2 is attached. The rear part of the beam has a curved contour 3and connects at its lower end with a rigid shoe 4:, the lattercomprising opposite members 5, having their upper edges at the forwardends reduced, as at 6, to provide a seat, and an intermediate socket 7to receive the lower rear end of the beam 1. The members 5 are closelybolted against each other, and the inner surfaces of their rearextremities are formed Serial No. 165,594. (No model.)

with oppositely-disposed recesses 8, which coincide when the two membersare applied to form a socket for the shank 9 of a depending plate 10,which extends downwardly below the lower edge of the shoe far enough toenter the soil and efiectively guide the plow, as well as to steady thegeneral structure. This plate is rigidly held in place by suitable boltsextending through openings 11, formed transversely through the rearwardportions of members 5, one of the bolts also extending through anopening in the plate.

A standard 12 is pivotally connected at its lower end to the frontextremity of the shoe and consists of two bars 13, spaced apart fromeach other and having their lower ends embracing the opposite sides ofthe forward extremity of the said shoe. The upper extremities of thebars 13 are connected by transverse bolts 14, spaced apart from eachother and arranged, respectively, in advance and in rear of the frontand rear edges of the curved portion 3' of the beam 1. The shovel,blade, sweep, or plowshare 15 is adjustably held on the lower extremityof the standard 12 by a bolt 16, which passes between the bars 13 of thestandard with its headed end against the rear edges of said bars and thenutted extremity against the upper portion of the outer surface of theplow blade, share, or sweep. By shifting the bolt 16 longitudinally ofthe standard the pointed end of the plow blade, share, or sweep may beprojected any distance desired below the lower end of the standard. Toregulate the angle of cut, the standard may be moved upwardly anddownwardly over the curved portion 3 of the beam 1. These adjustmentswill be advantageous in pursuing different kinds of plowing operations,and the seat 6 at the forward end of the shoe-bar twill permit the lowerportion of the standard to be adjusted without obstruction.

The handles 17 are preferably formed of wood, as usual, and providedwith upper curved grips 18 and have their lower ends angularly disposedand closely held in the upper angular extremity 19 of a connector 20,pivoted to the curved portion 3 of the beam 1 below the point ofengagement with the latter of the upper extremity of the standard 12.

The connector comprises opposite bars 21, held together by thefastenings passing through the rear extremity and the lower ends ofthehandles and by a front stop-bolt 22, extending transverselytherethrough in advance of the front edge of the curved portion of thebeam 3. A pivot-pin 23 passes through the bars 21 and the curved portionof the beam 3, so that the connector 20 may be raised or lowered at itsrear extremity within the limits of adjustment permitted by the pin 22,which engages the front edge of the curved portion 3 of the beam 1 atpredetermined points above and below the plane of the pivot-pin 23 tolimit the movement of the connector. Extending rearwardly from the beamis a pair of brace-bars 24:, having their rear ends adjustably attachedto the outer sides of the handles 17, the latter being provided with aseries of openings 25 for this purpose. By elevating or depressing thehandles,as desired, the heights of different plowmen may beacaccommodated and the plow more readily and practically directed bydifferent persons during the plowing operation.

The improved plow is adapted for general use by attaching theretoplow-blades of different forms and changing the adjustment of theseveral parts, particularly the standard and the plow-blades. By thismeans one plow is adapted to perform the work frequently requiringseveral individual plows having different structures.

Having thus fully described the invention, what is claimed as new is 1.A plow, comprising a beam having a downwardly-curved rear extremity, ashoe comprising opposite fiat members secured to each other and struckoutwardly at intermediate points to form a socket in which the lower endof the said rear extremity of the beam is secured, the upper portion ofthe front end of the shoe being reduced to provide a seat, asoil-entering guide-plate having its shank held between the rearportions of the members of the shoe and its lower end projeeting belowthe under edge of the shoe, a standard pivotally connected at its frontend to the forward extremity of the shoe, the upper extremity of thestandard movably embracing the rear downwardly-curved extremity of thebeam. a plow-blade adjustably secured to the lower part of the standard,and handles pivotally attached to the downwardlycurvedrear extremity ofthe beam below the point of engagement with the latter on the upper endof the standard.

2. A plow, comprising a beam having a downwardly-curved rear extremity,a shoe having an intermediate socket in which the lower end of thedownwardly-curved rear extremity of the beam is immovably secured, saidshoe being provided with a rear-depending soil-entering guide-plate andalso having the upper edge of its front extremity cutaway to form aseat, a standard pivotally connected at its lower end to the forwardextremity of the shoe and adjustable over the seat, the upper end of thestandard movably embracing the downwardly-curved rear extremity of thebeam, a plow-blade adjustably secured to the lower part of the standard,handles pivotally attached at their lower ends to the rear curvedextremity of the beam at a point below the engagement with the latter ofthe upper end of the standard, and brace-bars movably attached at theirfront ends to the beam .and having their rear terminals adjustablyengaging the handles.

In testimony whereof I affix my signature in presence of two witnesses.
